Description

  The present invention relates to a floor panel, and more particularly to a floor panel suitable for laying on a double floor called a free access floor in which a panel body is formed by aluminum die casting.

  Aluminum die-cast floor panels are relatively lightweight and have excellent strength as floor panels used for free access floor panels, so they have been widely used for free access floor floors. In order to provide strength, multiple ribs are formed on the back side of the panel, and when manufacturing high-strength products, it is possible to devise the number and arrangement of the ribs and to make the panel body thicker. It was.

  However, since the degree of freedom of design is low in order to devise the number of ribs and the arrangement shape of the ribs, in many cases, the panel body must be formed thick to cope with it. For this reason, not only the material cost becomes high, but also the handling property at the time of production and laying work becomes worse, and the cost for transportation and transportation becomes high, which is economically disadvantageous.

Moreover, in the conventional aluminum die-cast floor panel, when the surface (upper surface) of the floor panel (panel body) is plated or painted as a cover, the surface (upper surface) is subjected to post-processing such as buffing or shot blasting. Because it was necessary to pre-treat the casting surface (hot water flow pattern, hot wrinkles, etc.) peculiar to die casting products before plating or paint finishing, it has a good appearance for a high cost. There was a problem that the production efficiency was lowered due to the occurrence of failure without being obtained and the production cost was further increased. In addition, only a part of the plating or painting is damaged, and the floor panel itself is damaged.
Note that the above prior art known to the applicant of the present application is not related to the literature known invention, and therefore, prior art document information is not disclosed in the present specification.

  The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a floor panel that is lightweight and has high strength without much cost.

The floor panel according to claim 1 of the present invention that achieves the above object is composed of a panel body and a surface plate that are separately formed, at least the panel body is formed by aluminum die casting, and the upper surface of the panel body is It is characterized in that a front panel is integrally laminated.
Further, the floor panel according to claim 2 of the present invention is constituted by a panel main body and a surface plate as in the case of claim 1, and the panel main body forms a plurality of ribs on the upper surface of the bottom plate in the same body. Thus, the surface plate is integrally overlapped on the rib side upper surface of the panel body.
And the floor panel which concerns on Claim 3 of this invention is comprised by the panel main body and the surface mounting board similarly to Claim 1 and 2, Comprising: The said panel main body is separately formed into the baseplate and this baseplate. And an intermediate frame formed with a plurality of ribs having the same size or less, and the upper and lower plates are integrally overlapped with the intermediate frame in between. Is.
Further, the floor panel according to claim 4 of the present invention is composed of a panel main body and a cover plate as in the case of claims 1 to 3, but the panel main body has the same size or less as the cover plate. A plurality of the formed ribs are formed, and the cover plate is integrally overlapped on the upper surface of the panel body.

Thus, the floor panel according to the present invention is basically composed of a panel body and a surface plate, so that when the floor panel (panel body) is formed by aluminum die casting, the design can be freely compared with the conventional one. Even when manufacturing high-strength products, the strength design required for a floor panel can be facilitated, and at the same time, it is not necessary to respond by forming the panel body thickly as in the past. .
As a result, if the weight of the floor panel is the same, a product with higher strength can be provided, and it is possible to satisfy both weight reduction and strength enhancement at the same time.

In addition, since the upper surface of the panel body formed of aluminum die casting is covered with a cover plate, it is possible to apply a cover having a better appearance decoration than conventional products as a floor panel for a free access floor at a low cost.
In other words, the panel body molded by aluminum die casting is not affected by the casting surface (defects), and there is no need to perform special post-processing. Therefore, it is possible to easily apply a surface panel with excellent appearance aesthetics as a floor panel. At the same time, even if a part of the surface panel is damaged during the manufacture of the floor panel or after installation, Therefore, it is possible to provide a floor panel that is inexpensive as a whole.

  Further, in particular, according to the floor panel of claim 2, the panel body is formed by integrally forming a plurality of ribs on the upper surface of the bottom plate, and the cover plate is integrally stacked on the rib side upper surface of the panel body. Since they are configured together, the stress applied to the plurality of ribs is distributed to the bottom plate without concentrating on one place, so that the maximum load can be increased and a floor panel with higher strength can be obtained.

  Hereinafter, specific preferred embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the illustrated embodiments, and various variations are conceivable.

The floor panel A according to the present invention is basically composed of a panel main body 1 and a surface plate 2, and at least the panel main body 1 is formed by aluminum die casting, but the panel main body 1 has a plurality of ribs on the upper surface of the bottom plate 11. 12 is formed in the same body (see FIG. 1), and is formed from a separately formed bottom plate 13 and an intermediate frame 15 having a plurality of ribs 14 (see FIG. 2), There are cases where a plurality of ribs 14 formed to have the same size or less as the front panel are formed (see FIG. 3).
